This is getting to be a major problem. My load averages: 0.78, 0.99, 0.72. I have 1-3 running processes, a ton of sleeping processes, and my site is essentially unaccessible. I have tried disabling every plugin to no effect. My memory usage is less than half the 4096000K I am paying for and yet the site is so ridiculously slow when traffic is high.

Any ideas? Do I need to tweak an apache setting? My top is full of php5.cgi and apache2-psxxx like you’d expect.
